Traditional icons are most inspiring. You've got some nice
ones there. I've seen shops online that sell reproductions
and they can be rather costly. I've got a few little ones of
the Apostles, about 4x6, and they are quite nice to look at.
They help with Rosary meditations.
If you have any doubts, just ask a traditional priest, like
when you ask him to bless them.
It's most interesting to see the faithful of Eastern Churches
line up to touch and kiss their icons. They show great
reverence, and that's important for the Faith.
There was a traveling display of very rare original works
at the J. Paul Getty museum some years ago, and it was
quite odd to see so many people filing through, sort of
"standing in line" to view them, but the vast majority of
the people showed no conspicuous devotion - the guards
would not let anyone touch them, of course. It didn't
seem to be right, to treat these great icons as merely
material "works of art," as if they're just like all the other
fancy furnishings in other "displays." Some of them are
believed to have been made by contemporaries of the
Apostles, perhaps even the Gospel author, St. Luke, who
was an artist and a physician.
